Front features

The MPAD-C-A 12-24V Microwave presence detector

provides automatic control of low voltage loads including

lighting and BMS systems with optional manual control. The

MPAD-C-A 12-24V detects movement using a highly

sensitive microwave detector. This works by emitting low

power microwave signals and measuring the reflections as

the signals bounce off moving objects.

Functioning as a presence detector, the unit can turn lights

on when a room is occupied and off when the room is

empty. Optional settings allow lights to be turned off in

response to ambient daylight.

The MPAD-C-A 12-24V has a unique adjustable sensor

head that allows the area of detection to be optimised for

the application.

All functionality is fully programmable using an IR handset.

Detection Mode

The Detection Mode can be set to behave in Presence or Absence mode:

 Presence When movement is detected the load will automatically turn on. When the area is no longer

occupied the load will automatically switch off after an adjustable time period.

 Absence The load is manually switched on. When the area is no longer occupied the load will automatically

switch off after the adjustable time period has elapsed.

In either case, sensitivity to movement of the Microwave sensor can be adjusted using the Sensitivity parameter.

HINT: To assist in setting the Sensitivity, turn on the Walk Test LED which will flash red when movement is detected.

Switch Level On/Off

Occupancy detection can be made dependant on the ambient light level using the Lux On Level and Lux Off Level

parameters.

Ideal for large office or classroom

Ideal for corridor or aisle applications

Ideal for open plan areas and offices

Note. If the range is compromised by the ceiling construction /

material. Add the supplied 20mm spacer ring. See page 4 for

fitting details.

Installation

Absence detection

 To use absence detection a retractive (momentary) switch must be connected between the 2 terminals on the

diagram.

 The unit ships with presence detection as default. To change to absence detection, press and release the external

switch 5 times within the first minute of power up. The LED will turn on solid for 30 seconds to indicate absence

mode has been selected.

 To change back to presence detection, repeat the above procedure—the LED will flash for 30 seconds to indicate

presence mode has been selected.

Note: the above adjustments can also be made using the HHIR-PROG or HHIR-LCD-PROG handsets. See

When power is applied to the unit, the load will turn on immediately.

Set the timeout to 10 seconds, vacate the room or remain very still and wait for the load to switch off .

Check that the load switches on when movement is detected.

The unit is now ready for programming.

Power-up test procedure

Choosing a Suitable Location

The detector should be sited so that the occupants of the room fall inside the detection pattern shown opposite).

 Avoid positioning the unit where direct sunlight may enter the sensor element.

 Do not site the sensor within 1m of any lighting, forced air heating or ventilation.

 Do not fix the sensor to an unstable or vibrating surface.

 Avoid metallic objects directly in front of the sensor head.

The functionality of the MPAD-C-A 12-24V is controlled by a number of parameters which

can be changed or programmed by any of the following devices:

 HHIR-PROG Infrared Handset. See below for programmable functions.

 HHIR-LCD-PROG Infrared Handset (with LCD). See user guide for full

programming details.

For most basic programming operations the HHIR-PROG handset can be used and the following

procedures are based on using this device.

Point the handset at the Sensor and send the required programming commands to the unit as shown

below.

Valid commands will be indicated by a red LED flash. See page 1 for details of other LED responses.

What if the load does not turn ON?

 Check that the supply to the circuit is good.

 If the detection range is smaller than expected, check the diagram on page 2. Adjusting the angle of the sensor head

slightly may improve the detection range. If still reduced it may be compromised by the ceiling construction /

material. Add the supplied 20mm spacer ring. See page 4 for fitting details.

HINT: The Walk Test LED function can be used to check that the unit is detecting movement in the required area.

What if the load does not turn OFF?

 Ensure that the area is left unoccupied for longer than the Time Out Period.

 Ensure that the sensor is not adjacent to circulating air, heaters or lamps.

Detector Parameters

Walk Test LED Off On or Off

When set to On this causes a red LED to flash on the sensor when it detects

movement. Use this feature to check for adequate sensitivity levels.

 

Time Out

(Time adjustment)

20 minutes 0-99 minutes

Once the detector is turned on, this value sets how long the lights will stay on once

movement has ceased. Select 0 for 10 second delay – use for commissioning only.

 

Manual Time Out 10 minutes 0-99 minutes

When a manual operation occurs, either via the switch input or the infrared, it

invokes the timeout period.

Example 1: a detector in presence mode has a detector timeout of 15 minutes and

a manual timeout of 3 minutes. When the user leaves the room they press the off

button. The sensor will revert to automatic after 3 minutes, and then walking back

in the room will turn the lights on.

Example 2: using the settings above, the user turns the lights off (say for a

presentation) but stays in the room. Every time a movement is detected, the

manual timeout period is re-triggered, but when it doesn’t pick up for the short

timeout period, the sensor will timeout and revert to automatic. This means the

lights may turn on inadvertently during the presentation, if the occupants are still

for the manual timeout period, so adjust the timing carefully.

 

Sensitivity On 9 1 (min) to 9 (max)

Sensitivity level for detecting movement when the detector is already on. *HHIR-

PROG sets Sensitivity On and Off to the same value.

*



Sensitivity Off 9 1 (min) to 9 (max)

Sensitivity level for detecting movement when the detector is off. *HHIR-PROG

sets Sensitivity On and Off to the same value.

*



Lux time 0 0 (disabled)

1-99 minutes

If the detector measures the lux level and decides that the output needs switching

on or off as a consequence, the lux time must elapse first. If at any time during the

timed delay the lux change reverses then the process is cancelled. Lux Time

enables absence detection to be implemented with a lux off level set. When the

button is pressed, the lights will go on, regardless of ambient light level. However,

if there is sufficient ambient light, they will turn off again after the Lux Time. Note

that whenever the an external switch is pressed, whether in absence or presence

mode, if the lights were out because of the lux level, they will be immediately

turned on again for at least the Lux Time.

 

Power Up State On On or Off

Select No for a 30 second delay on start up. If Yes is selected, there will be no

delay on start up and the detector will always power up detecting.

 

Inhibit 4 seconds 1 to 999 seconds

When the detector turns off, a delay is instigated to prevent retriggering. In certain

circumstances this delay may not be enough. This parameter allows the delay to

be changed.
